Fix in fedora: 697cbe8643 I have a repetition of this:
SELinux is preventing /usr/sbin/usbmuxd from 'open' accesses on the file /run/udev/data/+usb:2-0:1.0.
***** Plugin catchall (100. confidence) suggests **************************
If you believe that usbmuxd should be allowed open access on the +usb:2-0:1.0 file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'usbmuxd' --raw | audit2allow -M my-usbmuxd
# semodule -i my-usbmuxd.pp

==================
what SRPM level contains the fix, so I might build and apply it?
Thank you
